Container system

Abstract

A container that may be used for retaining and dispensing matter is provided. The container includes a closure. The closure includes a top portion having an outer edge, a skirt downwardly depending from the outer edge and having an inside surface and a lower edge, and a plurality of spaced apart projections supported at the inside surface of the skirt. The projections are dimensioned such that a height of the projections in a vertical direction is greater than a width of the projection in a horizontal direction. The projections are configured to releasably engage an open end of the container for securing the closure to the container.

What is claimed is: 
     
       1. A closure for a container, the closure comprising:
 a top portion having an outer edge; 
 a skirt downwardly depending from the outer edge and having an inside surface and a lower edge; and 
 a plurality of spaced apart projections supported at the inside surface of the skirt, the projections defining a rectangular shape in a plane substantially parallel to the inside surface of the skirt and a triangular shape in a plane substantially perpendicular to the inside surface of the skirt with an upwardly facing surface that is downwardly sloped away from the inside surface of the skirt, and being dimensioned such that a height of the projections in a vertical direction is greater than a width of the projection in a horizontal direction, 
 wherein the projections are configured to releasably engage an open end of the container for securing the closure to the container. 
 
     
     
       2. The closure of  claim 1 , wherein each projection comprises a pair of substantially flat side walls. 
     
     
       3. The closure of  claim 1 , wherein the projections are spaced apart around the entire inner periphery of the skirt. 
     
     
       4. The closure of  claim 1 , wherein the closure is a substantially rectangular closure and the projections are only provided in one or more corner regions of the closure. 
     
     
       5. The closure of  claim 1 , further comprising a tear strip removably coupled to the lower edge of the skirt, the tear strip having an inside surface with at least one horizontal projection configured to engage a corresponding structure on the container, the horizontal projection being dimensioned such that a height of the horizontal projection in a vertical direction is less than a width of the horizontal projection in a horizontal direction. 
     
     
       6. A container comprising the closure of  claim 1 . 
     
     
       7. A closure for a container, the closure comprising:
 a top portion having an outer edge; 
 a skirt downwardly depending from the outer edge and having an inside surface and a lower edge; 
 a tear strip removably coupled to the lower edge of the skirt, the tear strip having a first end and a second end; 
 first and second pull tabs, the first pull tab coupled to the first end of the tear strip, the second pull tab coupled to the second end of the tear strip; 
 a first frangible link releasably coupling the first pull tab to the second pull tab and providing a substantially continuous transition between an upper edge of the first pull tab and an upper edge of the second pull tab; and 
 a second frangible link releasably coupling the first pull tab to the second pull tab and providing a substantially continuous transition between a lower edge of the first pull tab and a lower edge of the second pull tab. 
 
     
     
       8. The closure of  claim 7 , wherein the first and second pull tabs are offset outwardly from the skirt and the tear strip. 
     
     
       9. The closure of  claim 7 , further comprising third and fourth frangible links, the third frangible link extending between the skirt and the first pull tab, the fourth frangible link extending between the skirt and the second pull tab. 
     
     
       10. The closure of  claim 7 , wherein the first and second pull tabs each defining an aperture configured to receive the finger of a user. 
     
     
       11. The closure of  claim 7 , wherein the closure is a substantially rectangular closure defined by four sides, the first and second pull tabs being centrally located on one of the sides. 
     
     
       12. The closure of  claim 7 , wherein a portion of the skirt above the first and second pull tabs projects outwardly in an arcuate manner relative to the remaining portions of the skirt. 
     
     
       13. A container comprising the closure of  claim 7 .
